l 10 all whom t may concern:

Be it known that We, lViLLiAM O. BUN- NELL and OWEN G. VILLians, `citizens of the United States, residing at lVilkes-Barre, in the county of Luzerne and State 4of Pennsylvania, haveinvented certain new and useful Improvements in Attachments for Telephones; and we do declare the following to be a full, clear,` and exact description of the invention, such as will enable others skilled in the art to which" it appertains to make and use the same.

This invention relates vto improvements in attachments for telephones, particularly sanitary mouth piece coverings aiidV the means for changing saideovering from time to time. y y

The principal object ofthe invention is to provide means whereby a fresh sheet of antiseptic material maybe pulled across the mouth piece of a telephone upon which the device is secured each time the telephone re Iceiverisremoved from its hook. Y

Airadditional object is to'provide asimply tonstiaictedr sanitary attachment which caribe mounted upon practically any form telephone. y y

,With these and many other objects in View, the invention resides'in certain novel features of construction, combination and arrangement of parts which will be `here linafter moreV particularly described and Claimed and shown in the drawings wherein:

Figure 1 representsa perspective view of an ordinary desk telephone equipped With the improifed sanitary mouthpiece covering;

F ig. 2 is a vertical section' on the line l-Q of Fig. 3; and y c Fig. 3 is a similar view on the line 33 ofFig.2.` l'

`From the several figures of` the drawiijigs, it will'be noted that the mouth piece covering is adapted to be carried by a pair of rollers whichlare jour'naled in a frame, the latter'being clamped tothe standard S of `anordir'iary desktelephone T. The mouth piece of the transmitter of thistelephone is designated bythe letter M, the telephone receiverbears the character R and is supportedfbytlie usual hook H. l `The frame F consists oi an upright portien 1 having a spring clamp 2 formed integ-rally therewith, said clamp beingadjustably positioned `Qnthe standard S, and a.

number of arms which carry the operating means of the device. One of these arms designated by the numeral 3 extends for- Wardly from the upper end of the upright portion 1 and carries the antiseptic roll, the material of which isspread across the mouth piece between ai pair of rollers 4 and 5, the strip of material being pulled from the first mentioned roller Ll by the rotation of the roller 5. The lower ends of these rollers Jf and 5 are journaled in a bar 6, while the upper ends are similarly heldin spaced apart relation in a bar 7.

The lowerend of the feed roller 5 has a bevel gear 8 fixed Athereto which is continue ally in mesh with a similar gear 9, the latter being keyed to a horizontal shaft 10. This shaft is journaled in a suitable bearing 11 4carried by an additional portion 12 of the frame F. It will be noted that this horizontal shaft 11 extends rearwardly beneath the transmitter and at right anglesto the strip of antiseptic material covering themouth piece.

The rear end portion of the shaft 10, or the e'nd remote from that from which the gear 9 is'secui'ed, has an escape Wheel 13 keyedthereto, said Wheel having a plurality of notches 13 in its periphery. The eXtreme rear end of the shaft 10 beyond the whecl`1-5 is journaled in a plate 1etrising from the portion 12 of the frame F. Between this plate 14 and the escape Wheel 13 is positioned an ordinary spiral or clock spring 15 one end of which isV attached to the shaft 10 and the other to the plate 14.

A locking member 1G is provided for co operation with any one of said notches 13 to prevent the Wheel'from rotating when the spring 15 is Wound up. This lockinginember is mounted upon one end of a horizontal lever 17 which is pivoted intermediate 'ltS ends to the frame F. A colitlatillg SPT-111g 18 connected with the lever 17 Mid the Plat@ 14k holds the locking member in engagement ivith one of the notches. From this description it will be seen that Whenever the locking`` member 1G is released f roin'the notChGS 13. the shaft 10 Will be caused to rotate and that this movement will be transmitted t0 the feed roller 5 and cause the tllSQ/Pt@ material to Wind on thesame from tlle'Olel' roller 4, It is to be understood that the member 16 is held out of ellgtllel" 71th VVdevice in operation.

the escape wheel 13 to allow a quantity of antiseptic material equal to the distance between the two rollers 4 and 5 to wind upon the roller 5 from the roller4. Y

In order to release the locking member 1G at the proper time to permit the spring 15 to actuate the shaft 10 and the feed roller 5, a depending arm 19 is formed on the Outer end'of the horizontal lever 17. The posi tion of this lever and the depending arm is such that when the receiver R is lifted from the hook l-l it will necessarily engage the lower end of said arm and thus'rock the lever in a direct-ion vto release said locking member. As soon, however, as the receiver has been entirely removed from its hook and out ofengageinent with the' arm 19, the spring 18. will return the locking member into engagement with the periphery of the escape wheel 13 so that it will engage one ofthe notches 13 and arrest the movement of the mechanism.

r1`he operation of this mechanisniis'prevented when. the receiver is returned to its hook by the provision of a hingedend 2O of the depending arm 19. This end 20 it will be noted can swing only in one direction7 namely, inwardly, thus when the receiver is returned to its hook, said end 20 willY be swung to the position shown in dotted lines inFig. 2. y

It is believed that the operation of the device is readily evidentl from the several figures in the drawings but briefly described and is as follows Assuming that the frame F carrying the operating mechanism and the rollers 4 and 5 khave been correctly adjusted with respect to the receiver R, the end of the antiseptic strip which is wound upon the roller 4 is fixed to the feed roller 5 and partially wound tlierearound. This strip of material which covers the mouth piece end will prevent the accumulation of Vdisease germs thereon. The parts are now in position to beoperated by the user of the telephone, who, when he removes the receiver from the hook automatically sets the As hereinbefore mentioned, such removal of the receivei' causes the upper end thereof to engage the end of .thedependingarm 19 and disengages the locking member 16 from one ofthe notches 13 a sufficient length of time to permit the spring 151 which has been previously wound up to rotate the shaft 10 and the feed roller 5V to pull a new strip of antiseptic material from the roller 4 and wind it around the roller 5. This strip of material remains in place after the receiver has beenreturned toits hook anduntil another person removes the receiver for further operationv of the telephone. l

IThese movements are repeated until all v.of the material has been wound from the roller, 4 upon theV roller 5, and by this time the spring 15 has been nearly completely unwound. In order to rewind the same, the end of the strip of antiseptic'material' which -was formerly on the roller4 -is-pulled until the entire strip has been-removedfroni the roller 5, said roller being rotated during this ^reinov`al, the rotation thereof being transmitted to the shaft 10 and to the spring 15. A :new roll of material may then be placed upon the roller 4 as hereinbefore mentioned.
